電磁誘導加熱式の調理器は、内鍋の直下に配置した電磁誘導加熱コイルによって発生する渦電流で内鍋そのものを発熱させるものであるが、電磁誘導加熱コイルによって発生する磁界が下方に漏れると、その影響でテーブル上の金属が発熱する可能性がある。そのため、従来の電磁誘導加熱式の調理器では、特許文献１に開示されているように、電磁誘導加熱コイルの下方に棒状のフェライトコアを放射状に配置することが行われている。   An electromagnetic induction heating type cooking device heats the inner pan itself with eddy currents generated by an electromagnetic induction heating coil placed directly under the inner pan, but when the magnetic field generated by the electromagnetic induction heating coil leaks downward As a result, the metal on the table may generate heat. Therefore, in a conventional electromagnetic induction heating type cooker, as disclosed in Patent Document 1, rod-shaped ferrite cores are radially arranged below the electromagnetic induction heating coil.

しかしながら、従来の電磁誘導加熱式調理器では、電磁誘導加熱コイルによって発生する磁界の側方への漏れを防止するため電磁誘導加熱式の調理器、例えばＩＨ炊飯器などでは、特許文献１に図示されているように、合成樹脂製の胴が採用されており、全体としてコストアップの一因ともなっていた。
However, in a conventional electromagnetic induction heating cooker, an electromagnetic induction heating cooker such as an IH rice cooker is illustrated in Patent Document 1 in order to prevent the leakage of a magnetic field generated by an electromagnetic induction heating coil to the side. As mentioned above, a cylinder made of synthetic resin was adopted, which contributed to the cost increase as a whole .

上記、従来技術の欠点に鑑み、本発明は磁界の側方への漏れを防止するために、電磁誘導加熱コイルと胴の間に胴反射板を配置するとともに、磁界の側方への漏れだけでなく、前方及び／又は後方への磁界の漏れを簡易な構造によって防止する構造を実現することを目的とするものである。
In view of the above-mentioned drawbacks of the prior art, the present invention has a trunk reflector disposed between the electromagnetic induction heating coil and the trunk in order to prevent leakage of the magnetic field to the side, and only leakage of the magnetic field to the side.

In the invention according to claim 2, the body reflecting plate 11 is formed integrally with a flat bottom surface portion 11a and side surface portions 11b on both left and right sides of the bottom surface portion 11a . Lead wires are arranged between 11b .

請求項１記載の本発明電磁誘導加熱調理器における胴反射板11の取付け構造によれば、電磁誘導加熱コイル８によって発生する磁界の側方への漏れが胴反射板11によって防止され、金属製の胴２であっても、電磁誘導加熱コイル８から漏れる磁界によって発熱することを防止することができるとともに、電磁誘導加熱コイル８による磁界の漏れをより確実に防止することができる。特に、金属製とした胴２の背面部分の発熱や本体内部における磁界の影響を少なくすることができる。
According to the mounting structure of the trunk reflector 11 in the electromagnetic induction heating cooker according to the first aspect of the present invention, the leak of the magnetic field generated by the electromagnetic induction heating coil 8 to the side is prevented by the trunk reflector 11 and is made of metal. Even in the case 2, it is possible to prevent heat from being generated by the magnetic field leaking from the electromagnetic induction heating coil 8, and it is possible to more reliably prevent leakage of the magnetic field by the electromagnetic induction heating coil 8. In particular, it is possible to reduce the influence of heat generation on the back surface of the body 2 made of metal and the magnetic field inside the main body .

請求項２記載の発明によれば、請求項１記載の発明を実施する上において、胴反射板11の組み立てをより簡単に行うことができる。
According to the second aspect of the present invention, in practicing the invention described in claim 1, it can be easily performed Ri by the assembly of the cylinder reflector 11.

図１は、本発明を応用した炊飯器全体の縦断面図である。この電気炊飯器は、底体１と胴２で構成する本体の内部に内鍋３を収容し、その上面を蓋４によって密閉し、電磁誘導加熱によって炊飯の調理を行うものである。内鍋３は、肩部材５の開口部に固定した内胴６と椀形に成型した保護枠７によって形成される収容部に着脱自在に収容し、内鍋３の下底部を支持する保護枠７の下方に配置した電磁誘導加熱コイル８に、高周波電流を通電することによって発生する渦電流のジュール熱によって内鍋３を発熱させ、炊飯などの調理を行うものである。   FIG. 1 is a longitudinal sectional view of the entire rice cooker to which the present invention is applied. In this electric rice cooker, an inner pot 3 is accommodated in a main body constituted by a bottom body 1 and a body 2, the upper surface thereof is sealed with a lid 4, and cooking of rice is performed by electromagnetic induction heating. The inner pot 3 is detachably accommodated in an accommodating portion formed by an inner trunk 6 fixed to the opening of the shoulder member 5 and a protective frame 7 molded into a bowl shape, and a protective frame that supports the lower bottom portion of the inner pot 3 The inner pot 3 is heated by Joule heat of eddy current generated by energizing a high-frequency current to the electromagnetic induction heating coil 8 disposed below 7, and cooking such as rice cooking is performed.

保護枠７の下方に配置する電磁誘導加熱コイル８の下方には、図２に示すように複数のフェライトコア９，９を放射状に配置している。このフェライトコア９は、保護枠７の底面の中央部と外周の傾斜部分の二箇所に配置している電磁誘導加熱コイル８(8A及び8B)を跨ぐように配置することによって、下方への磁束の漏れをできるだけ少なくし、炊飯器を置いたテーブル上などの器外にある金属が発熱する現象を防止している。フェライトコア９は、合成樹脂材で成型した保持部材10に保持させ、該フェライトコア９を保持させた保持部材10を保護枠７に固定している。   A plurality of ferrite cores 9 and 9 are radially arranged below the electromagnetic induction heating coil 8 arranged below the protective frame 7 as shown in FIG. The ferrite core 9 is disposed so as to straddle the electromagnetic induction heating coils 8 (8A and 8B) disposed at the central portion of the bottom surface of the protective frame 7 and the inclined portion of the outer periphery, thereby providing a downward magnetic flux. As much as possible, it prevents the metal on the outside of the table such as the table where the rice cooker is placed from generating heat. The ferrite core 9 is held by a holding member 10 molded from a synthetic resin material, and the holding member 10 holding the ferrite core 9 is fixed to the protective frame 7.

フェライトコア９とは別に保護枠７の下方、すなわちフェライトコア９と底体１の間に例えばアルミニウム板などで製作した、金属製の胴反射板11を配置する。フェライトコア９と底体１の間に金属製の胴反射板11を配置すると、下方への磁束の漏れをより効果的に防止することができる。しかしながら、本発明では、図４に示すように平板状に形成した胴反射板11の、左右両側部分を上方に立ち上げることによって、電磁誘導加熱コイル８と胴２との間に胴反射板11の一部を位置させ、磁界の側方への漏れをも防止するようにしている。   Apart from the ferrite core 9, a metal body reflector 11 made of, for example, an aluminum plate is disposed below the protective frame 7, that is, between the ferrite core 9 and the bottom body 1. If a metallic body reflector 11 is disposed between the ferrite core 9 and the bottom body 1, leakage of magnetic flux downward can be prevented more effectively. However, in the present invention, as shown in FIG. 4, the left and right side portions of the body reflector 11 formed in a flat plate shape are raised upward, so that the body reflector 11 is interposed between the electromagnetic induction heating coil 8 and the body 2. Is located to prevent leakage of the magnetic field to the side.

すなわち、図示実施形態の胴反射板11は、図２及び図３に示すように、電磁誘導加熱コイル８のうち中央部の電磁誘導加熱コイル8Aを完全に覆うことができる大きさの略六角形に形成した底面部11aの側辺を延長し、傾斜部11cを介して側面部11bを上方に立ち上げている。この側面部11bが金属製の胴２と電磁誘導加熱コイルの間に位置するため、側方への磁界の漏れを防止することができ、胴２の発熱現象を回避することができる。   That is, as shown in FIGS. 2 and 3, the body reflector 11 of the illustrated embodiment has a substantially hexagonal shape with a size that can completely cover the electromagnetic induction heating coil 8 </ b> A at the center of the electromagnetic induction heating coil 8. The side of the bottom surface portion 11a formed in the above is extended, and the side surface portion 11b is raised upward via the inclined portion 11c. Since the side surface portion 11b is located between the metal cylinder 2 and the electromagnetic induction heating coil, the leakage of the magnetic field to the side can be prevented, and the heat generation phenomenon of the cylinder 2 can be avoided.

底面部11aと側面部11bを一体に形成する胴反射板11は、図３に示すように略六角形の底面部11aの左右両側縁を延長して傾斜部11cを、さらに延長して側面部11bを形成する。底面部11aの中心には比較的大きな貫通孔12を穿設するとともに、四箇所に小さな貫通孔13，13を穿設している。中心部分の貫通孔12は、保護枠７の底面中心部に突出させたボス15を通過させるためのものである。四箇所の小さな貫通孔13は、保護枠７の底面に突出させた突起16，16に係合させることによって正確な位置を保持させるものである。
なお、図２に示すように、保護枠７の四隅部分には円筒状の取付け筒14，14が配置してあり、該取付け筒14を底体１内面に突出させた取付け部にビス止めなどの手段によって、底体１に対して四点で支持され、しっかりと締め付け固定することができるようになっている。 As shown in FIG. 3, the body reflector 11 integrally forming the bottom surface portion 11a and the side surface portion 11b extends the left and right side edges of the substantially hexagonal bottom surface portion 11a to extend the inclined portion 11c, and further extends the side surface portion. 11b is formed. A relatively large through-hole 12 is drilled in the center of the bottom surface portion 11a, and small through-holes 13 and 13 are drilled at four locations. The through-hole 12 in the center part is for allowing the boss 15 projected from the center part of the bottom surface of the protective frame 7 to pass therethrough. The four small through-holes 13 are held in accurate positions by engaging with the projections 16, 16 protruding from the bottom surface of the protective frame 7.
As shown in FIG. 2, cylindrical mounting cylinders 14 and 14 are disposed at the four corners of the protective frame 7, and screws are attached to the mounting portion where the mounting cylinder 14 protrudes from the inner surface of the bottom body 1. By this means, it is supported at four points with respect to the bottom body 1 and can be firmly tightened and fixed.

上記構造の胴反射板11の側面部11bには、被覆電線などのリード線17，17を保持させるためのリード線支持部18，18を形成している。
その他、保護枠７の底面に突出させる突起の一部又は全部を単なる円柱状ではなく、図５に示すように略円錐形に形成し、突起の基部に胴反射板11が嵌り込む段部19を形成しておくのが取り扱い上便利である。
Lead wire support portions 18 and 18 for holding lead wires 17 and 17 such as covered electric wires are formed on the side surface portion 11b of the body reflector 11 having the above structure .
In addition, a part or the whole of the protrusion protruding from the bottom surface of the protective frame 7 is not a mere columnar shape but is formed in a substantially conical shape as shown in FIG. 5, and a step portion 19 in which the body reflector 11 is fitted in the base of the protrusion. It is convenient for handling to form.

側方への磁界の漏れを防止するには、図示例の胴反射板に限らず、側面部分のみの反射板を配置することによって、側方への磁界の漏れを防止することもできる。このような側面部分のみの胴反射板は平板状に形成し、その下端部を底体１に、上端部を保護枠７の上部に支持させることによって配置することができる。しかしながら、図示例のように、底面部11aと側面部11bを一体に形成することによって、側方及び下方への磁界の漏れをより効果的に防止することができるとともに、その組み立て作業を能率的に行うことが可能となる。   In order to prevent the leakage of the magnetic field to the side, it is possible to prevent the leakage of the magnetic field to the side by arranging not only the body reflection plate of the illustrated example but also the reflection plate of only the side surface portion. Such a body reflection plate having only a side surface portion is formed in a flat plate shape, and can be disposed by supporting the lower end portion thereof on the bottom body 1 and the upper end portion thereof on the upper portion of the protective frame 7. However, as shown in the example, by integrally forming the bottom surface portion 11a and the side surface portion 11b, leakage of the magnetic field to the side and the bottom can be prevented more effectively, and the assembly work can be efficiently performed. Can be performed.

次に、図示実施形態の反射板11の組み立て方法を説明する。
図２に示すように、保護枠７の底面に予め電磁誘電加熱コイル８及び保持部材10に保持されたフェライトコア９を装着しておく。そして、電磁誘導加熱コイル８及び保持部材10に保持されたフェライトコア９が装着された保護枠７に、フェライトコア９の表面を覆うように胴反射板11を装着する。胴反射板11を装着するには、保護枠７の底面に突出している突起16，16に、胴反射板11の底面部に穿設した貫通孔13，13を嵌め込むことによって、胴反射板11が正確に位置決めされる。このとき、突起16の一部を図５に示すような円錐形に形成し、その基部に段部19を形成しておくと、装着した胴反射板11が段部19に係合し、保護枠７から脱落しないため、組み立て作業などに際して取り扱いに便利である。また、保護枠７の上端部に形成した外鍔7aの下面に、反射板11の側面部11b上端を支受する細幅の受け部20を形成しておくのが好ましい。 Next, a method for assembling the reflector 11 of the illustrated embodiment will be described.
As shown in FIG. 2, a ferrite core 9 held in advance by an electromagnetic dielectric heating coil 8 and a holding member 10 is attached to the bottom surface of the protective frame 7. Then, the body reflector 11 is attached to the protective frame 7 to which the ferrite core 9 held by the electromagnetic induction heating coil 8 and the holding member 10 is attached so as to cover the surface of the ferrite core 9. In order to mount the trunk reflector 11, through-holes 13, 13 drilled in the bottom surface of the trunk reflector 11 are fitted into the projections 16, 16 projecting from the bottom of the protective frame 7. 11 is accurately positioned. At this time, if a part of the projection 16 is formed in a conical shape as shown in FIG. 5 and a step portion 19 is formed at the base thereof, the mounted body reflector 11 is engaged with the step portion 19 to protect it. Since it does not fall off from the frame 7, it is convenient for handling during assembly work. Further, it is preferable to form a narrow receiving portion 20 that supports the upper end of the side surface portion 11b of the reflecting plate 11 on the lower surface of the outer casing 7a formed on the upper end portion of the protective frame 7.

すなわち、胴反射板11の側面部11b上端を保護枠７の外鍔7aに形成した受け部20に差し込みながら、突起16を貫通孔13に差し込み、側面部11b上端を段部19に係合させることによって胴反射板11が保護枠７に保持され、この胴反射板が保持された保護枠を底体１にしっかりと固定する。底体１に対する保護枠７の固定方法は任意であるが、保護枠の四隅をビス止することによって確実に、かつ強固に締め付け固定することができる。   That is, while the upper end of the side surface portion 11b of the body reflector 11 is inserted into the receiving portion 20 formed on the outer casing 7a of the protective frame 7, the protrusion 16 is inserted into the through hole 13 and the upper end of the side surface portion 11b is engaged with the step portion 19. Thus, the trunk reflector 11 is held by the protective frame 7, and the protective frame holding the trunk reflector is firmly fixed to the bottom body 1. Although the fixing method of the protective frame 7 to the bottom body 1 is arbitrary, it can be securely fixed firmly by fastening the four corners of the protective frame with screws.

底体１内面の所定位置、すなわち保護枠７を配置する中心位置には、低い高さで大小二つの円筒状リブ21，22を形成している。また、保護枠７の中心部には、前記底体に形成した大径の円筒状リブ22と小径の円筒状リブ21の中間の直径の円筒状リブ23を突出形成している。この、保護枠７下面の中心に形成した円筒状リブ23は、放射状に配置するフェライトコアの保持部材10内端が当接する位置決め機能を兼ねたものである。   Two small and large cylindrical ribs 21 and 22 are formed at a predetermined position on the inner surface of the bottom body 1, that is, at the center position where the protective frame 7 is disposed. Further, a cylindrical rib 23 having a diameter intermediate between the large-diameter cylindrical rib 22 and the small-diameter cylindrical rib 21 formed on the bottom body is formed at the center of the protective frame 7. The cylindrical rib 23 formed at the center of the lower surface of the protective frame 7 also serves as a positioning function for abutting the inner end of the holding member 10 of the ferrite core arranged radially.

しかして、胴反射板11を保持させた状態の保護枠７を底体１の定位置に配置し、保持枠７を底体１に締め付け固定すると、反射板11の底面部11a中心位置において、下から円筒状リブ21及び22によって支受され、上方から保護枠７に形成された円筒状リブ23によって押圧される。換言すれば、底体１の円筒状リブ21，22と保護枠７の円筒状リブ23によって挟持され、その締め付け力は、保護枠７を底体１に固定する強い力であるため、胴反射板11がガタ付いたり、盲動するようなことなくしっかりと固定されることになる。   Thus, when the protective frame 7 holding the case reflector 11 is disposed at a fixed position of the bottom body 1 and the holding frame 7 is fastened and fixed to the bottom body 1, at the central position of the bottom surface portion 11 a of the reflector 11, It is supported by cylindrical ribs 21 and 22 from below and is pressed by cylindrical ribs 23 formed on the protective frame 7 from above. In other words, it is sandwiched between the cylindrical ribs 21 and 22 of the bottom body 1 and the cylindrical rib 23 of the protective frame 7, and its tightening force is a strong force for fixing the protective frame 7 to the bottom body 1, so The board 11 will be firmly fixed without rattling or blinding.

胴２を筒状の金属製とする場合、底体１の中心位置に内鍋３を配置すると、電磁誘導加熱コイル８と胴の側面部分が最も接近することになるため、電磁誘導加熱コイル８による磁界の影響が最も大きい。したがって側面部分にのみ胴反射板を配置することによって胴の発熱現象を効果的に防止することができる。しかしながら、前方や後方からの磁界の漏れによって胴が加熱される可能性がある場合や、前後方向の磁界の漏れが本体内の機器に対して好ましくない影響を与える場合がある。このような事態に対応するため本発明は、胴反射板の側面部11b，11bの間にリード線17を掛け渡す。このように、リード線17を掛け渡すことによってもある程度磁界の漏れを防止することができ、胴反射板11の効果をより一層向上させることができる。リード線17は、胴反射板11の前方部分又は後方部分のいずれか一方、もしくは双方に配置することができる。 When the body 2 is made of a cylindrical metal, the electromagnetic induction heating coil 8 and the side surface portion of the body are closest to each other when the inner pot 3 is disposed at the center position of the bottom body 1. The effect of magnetic field due to is the largest. Therefore, by disposing the body reflector only on the side surface portion, the heat generation phenomenon of the body can be effectively prevented. However, there is a possibility that the body may be heated by the leakage of the magnetic field from the front or the rear, or the leakage of the magnetic field in the front-rear direction may have an unfavorable effect on the devices in the main body . Such a situation the present invention to correspond to the side surface portion 11b of the cylinder reflector, to pass over the lead wire 17 between 11b. As described above, the leakage of the magnetic field can be prevented to some extent also by passing the lead wire 17, and the effect of the trunk reflector 11 can be further improved. The lead wire 17 can be disposed on either or both of the front part and the rear part of the body reflector 11.
